Application
Naphthenic acid is commonly used in the synthesis of useful metal naphthenates such as copper naphthenate, a wood preservative; titanium naphthenate, a precursor for the preparation of titanium oxide thin films and a rare earth naphthenate, a lubricant oil additive. It can also be in the synthesis of biodegradable naphthenic acid ionic liquids.

Naphthenic acids (NAs) are an important group of trace organic pollutants predominantly comprising saturated aliphatic and alicyclic carboxylic acids. NAs are ubiquitous; occurring naturally in hydrocarbon deposits (petroleum, oil sands, bitumen, and crude oils) and also have widespread industrial uses.

Oil sands process-affected waters (OSPWs) produced during the extraction of bitumen at the Athabasca Oil Sands (AOS) located in northeastern Alberta, Canada, are toxic to many aquatic organisms. Much of this toxicity is related to a group of dissolved organic
